Personally: Hiking, biking, photography, DnD, and fixing things.
It sounds like a lot (because it is lol) but with ADHD having a group of hobbies I can orbit around (especially if they can overlap (like these ones))can help me avoid diving into too many new hobbies.
Same as yours, but instead of cultivating them, I spend my time doomscrolling.
Avoiding the doomscroll is so hard a lot of days
